Not entertaining girl, American, when visiting China (9)

I believe the answer is:

unamusing

'not entertaining' is the definition.

'girl american when visiting china' is the wordplay.
'girl' becomes 'una' (**).
'american' becomes 'us'.
'when visiting' indicates putting letters inside.
'china' becomes 'ming' (I've seen this before).
'us' put into 'ming' is 'musing'.
'una'+'musing'='UNAMUSING'

(Another definition for unamusing that I've seen is " it isn't funny".)

I've seen this clue in The Times.
